Cloud Infrastructure Engineer

  • Kiyosumi Shirakawa, Tokyo, Japan
Data Production Department

Job description

The Data Production Department is responsible for satellite operations, image data production, and distribution of data products of our proprietary small SAR (synthetic aperture radar) satellites, the "StriX" series.

The Satellite Operation Planning Unit has the responsibility of making operation plans of our satellites, generating commands for the satellites based on the operation plans, and registering the generated commands to our satellite control system. The unit is also responsible for data management necessary for operations.


In this position, as a member of the Data Production Department, you will join the Satellite Operation Planning Unit which is responsible for developing and operating the Spacecraft Control Subsystem for our small SAR satellite constellation "StriX" series. The Spacecraft Control Subsystem is one of the subsystems to operate our satellite constellation. Our responsibility is to keep the system working reliably at all times.

Details of work:

The roles of the Spacecraft Control Subsystem are making operation plans for our satellites, generating commands for them, and calculating specific information of our satellites such as past and future position and velocity data to use them in the planning process.
Since this is an in-house system development, we will not only develop but also operate the system to add and improve future functions.
The person in this position has the responsibility to maintain and update the infrastructure of the Spacecraft Control Subsystem, and achieve continuous improvement without any troubles. The person will also collaborate with other infrastructure engineers in the company to introduce best practices to our system, support development and operation of other systems.

Selling points of this role:

We’ve already operated 3 satellites in orbit, and the number of satellites will increase rapidly in the near future. Because the Spacecraft Control Subsystem has already been used for our daily operations, we cannot perform our daily satellite operations without it. You will be involved in the maintenance and operation of such an important system.

You will be also involved in the core of our business by maintaining the Spacecraft Control Subsystem because it has interactions with our data platform which is used as the frontend to customers, and the Data Processing Subsystem which generates SAR products.

Now we plan to expand our satellite constellation rapidly and we are required to operate our satellites with more stability and less personal effort. You will be able to show your skill and grow yourself through achieving these requirements.
